Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an image formation device and program that can make a quick determination of an attachment failure of a developer storage body in comparison with a case when detecting that concentration of a control image is thinner than a predetermined value.SOLUTION: An image formation device comprises: an image formation device main body; a developer storage body that is detachably and attachably mounted to the image formation device main body, and stores developer; an image holding body that holds a developer image developed by the developer supplied from the developer storage body; concentration detection means that detects concentration of a control image formed for concentration control in the image holding body; and control means that forms the control image plurality of times in a time span, detects the concentration of the control image formed plurality of times by the concentration detection means, and controls so as to determine an attachment state of the developer storage body on the basis of a change in concentration of the detected control image.SELECTED DRAWING: Figure 5
【課題】制御用画像の濃度が予め定めた値よりも薄くなったことを検出する場合と比較して、現像剤収容体の取付け不良判定を早く行うことができる画像形成装置及びプログラムを提供する。【解決手段】画像形成装置は、画像形成装置本体と、前記画像形成装置本体に取外し、取付け自在に装着され、現像剤を収容する現像剤収容体と、前記現像剤収容体から供給された現像剤により現像された現像剤像を保持する像保持体と、前記像保持体に濃度制御のために形成された制御用画像の濃度を検出する濃度検出手段と、時間を空けて複数回制御用画像を形成し、複数回形成された制御用画像の濃度を前記濃度検出手段により検出し、検出された制御用画像の濃度変化に基づいて前記現像剤収容体の取付け状態を判定するように制御する制御手段と、を有する。【選択図】図5 |
